Abstract: Database report generation technology for handling a single logical query that requires data that is physically located in two different sources. The system uses intelligent push-down joins, which move data from one source to the other and join data within that source. The system dynamically determines which direction to move data depending on how the data is used in a query.

When mounting the first hard disk drive, the fasteners extend through the first fastening holes to mount the first hard disk drive, and the adapter assembly is detachably mounted to second ends of the sidewalls, to couple to the first hard disk drive. When mounting the second hard disk drive, the fasteners extend through the second fastening holes to mount the second hard disk drive in the receiving space.

Abstract: A mounting device comprises two sidewalls, a connecting portion defining a receiving slot, a fixing member, and a latching member slidably received in the receiving slot. A blocking piece and a connecting wall are connected between a top wall and a bottom wall of the receiving slot. A first end of the fixing member forming two projections is pivotably connected to the first end of the connecting portion. The projections are received in the receiving slot. A tab extends from a second end of the fixing member. The latching member comprises a plate blocked by the blocking piece, and an extension piece blocked by the connecting wall. The fixing member is pivoted toward the latching member to allow the projections to extend out of the receiving slot. The latching member is slid toward the fixing member to block the tab.

Abstract: A method for activating network storage includes: a message processing server receives a network storage request from a client; the message processing server establishes a session with a history function (HF) according to the network storage request, and sends the content from the session in which the client participates to the HF through the session with the HF. A system for activating network storage, a message processing server, and a client are also provided. With the present invention, the network storage is implemented more conveniently, and the user experience is improved.

Abstract: A fixing device for fixing two connectors connected to each other includes two holding members and a connecting member connected between the holding members. Each holding member includes a connecting piece and two arms extending down from opposite ends of the connecting piece to sandwich one of the connectors.

Abstract: A supporting bracket includes two opposite sidewalls, a first end wall connected between front ends of the sidewalls, a second end wall connected between rear ends of the sidewalls, and an air guiding plate slantingly connected between lower parts of the sidewalls. The air guiding plate extends up from the first end wall toward the second end wall. A top of the air guiding plate and the sidewalls bound a cooling area communicating with an inside of the supporting bracket. An air inlet of the cooling area is defined between the first end wall and the air guiding plate.

Abstract: A rack-mount server assembly includes a rack, a server module mounted in the rack, a switch mounted in the rack and above the server module, cables connected between the server module and the switch, and a cable management apparatus. The switch and the server module cooperatively bound a space. The cable management apparatus includes a frame mounted to the rack and covering the space, a sliding member slidably installed in the frame, and an air shield member mounted on an end of the sliding member. The frame defines a through hole aligning with the space for the cables extending through. The sliding member is slid to allow the air shield member to cover or uncover the space. The cables extend through the air shield member in response to the air shield member covering the space.

Abstract: A central processing unit socket assembly includes a socket mounted on a circuit board, a locking apparatus, and a cover. The cover includes a main plate, a resilient first locking portion formed on a first end of a first surface of the main plate, a second locking portion formed on a second end of the first surface of the main plate opposite to the first locking portion, and a number of connecting pins protruding out from a second surface of the main plate opposite to the first surface of the main plate. The first and second locking portion of the first surface of the cover can be detachably latched to the socket. The connecting pins can be connected on the locking apparatus.
